The problem:
A ball accelerates at 8 cm/s^2 for 3 seconds, starting with velocity 12 cm/s.
• What will be its velocity after the 3 seconds has elapsed?
answer/question/discussion: ->->->->->->->->->->->-> :
Using the formula a= vf-vo over change in time. Then vf will 36cm/s.
• Assuming that acceleration is constant, what will be its average velocity during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
The average velocity will be equal to 36 + 12 over 2 which is equal to 24cm/s.
• How far will it travel during this interval?
answer/question/discussion: ->->->->->->->->->->->-> :
Using the formula vAve = change in distance over change in time. The change in distance will be equal to 24*3 which is equal to 72cm.
